Copper Reduction in QMA's Wastewater Using TMT [PDF]Abstract: QMA, Inc. is located at 1390 Lunt Avenue in Elk Grove Village, IL. The company makes printed wiring boards (PWBs) and employs about 40 people. QMA wanted to reduce the cost of disposing of its wastewater which was being hauled off site. The company also wanted to improve workplace safety by eliminating 3,000 gallons of highly acidic wastewater which had to be stored in the plant awaiting disposal. QMA company ofﬁcials attended a workshop presented by the Illinois Waste Management and Research Center (WMRC) for the printed wiring board sector and asked WMRC for assistance. This factsheet details a pilot project performed by WMRC scientists to demonstrate the use of TMT to reduce copper contaminant in QMA's wastewater. The pilot treatment process convinced QMA to adopt the use of TMT for treatment of its wastewater, resulting in a safer workplace and an annual savings of $20,000.
